A gate that won't move is a security problem today — and an expensive mistake tomorrow if the wrong person touches it. Here is what to verify before you approve any repair.
Openers, hinges, tracks, rollers, sensors, and control boards fail far more often than gates do. A full-replacement quote made without a diagnosis skips the step that protects your money: finding the failed component first. The right first step is always the same: find the failed component, then decide what repair actually makes sense.

Gates combine welding, electrical, and automation — ask for the license number and insurance before work is quoted. Top Tier Building Services Inc. operates under CA General Contractor License #1146790 and is licensed, bonded, insured, and workers' comp covered.
Is it the opener motor, the control board, the track and rollers, a hinge, or power and wiring? A company that names the failed component — and shows you — has actually diagnosed the problem instead of estimating around it.
Opener brands matter: parts availability decides whether your gate is fixed this week or waiting a month. Ask what they stock and service — and whether your model is among them.
Automatic gates must reverse on obstruction — entrapment protection is a safety standard, not an option. Any repair visit should test and document photo eyes and reversal behavior.
Ask what the diagnostic visit costs and whether it applies toward the repair. Clear trip-fee terms now prevent invoice surprises later.

A failed roller or board becomes a whole-gate quote. Demand the component-level diagnosis first.
If entrapment protection never comes up, the company is skipping the one check that protects your family and your liability.
"We'll see when we get there" pricing usually ends in a number you never agreed to.
The fastest path back to a working gate starts with knowing exactly what failed — which is why the process starts with your description and photos, not a price.
Won't open, won't close, moves partway, makes noise, off track, or dead remote and keypad.
A photo of the gate, opener unit, and any damage — or a short video of the fault — speeds the diagnosis.

The usual suspects, in order: power supply, remote or keypad batteries, blocked or misaligned photo eyes, a failed opener motor or control board, or a gate physically off its track or hinge. Most are component repairs, not gate replacements.
If the frame and structure are sound, repair usually wins — openers, boards, rollers, and hinges are all replaceable. Replacement makes sense when the gate itself is rusted through, badly damaged, or you want a different style or automation level.
Which component failed, parts availability for your opener brand, whether welding or fabrication is involved, and access and wiring conditions. A component-level diagnosis with a written quote is the only reliable number.
